7 Claims. (CI. 20-62) This invention relates towindows and, more particularly, to jalousie windows having an improved means for closing the window sections.

I Jalousie windows have been used extensively for some time in localities of relatively warm climate where the problem of keeping outside cold air from entering between the window sections has not been too great. Many attempts have been made to develop a window construction that has all the advantages of a jalousie window and will, in addition, form an air-tight window when closed so that it is satisfactory for use in colder climates. The constructions commonly used have not been satisfactory as all of the window sections will not form the required air-tight seal when the window sections are closed.

The present invention serves to furnish a jalousie window construction which is satisfactory for use in colder climates and will provide a relatively tight air seal when the window is in closed position, thereby enabling it to be used in colder climates.

The purpose of the invention also is to provide a jalousie window construction wherein the individual panes of glass or other transparent material are readily replaceable.

The invention is described in greater detail in connection with the accompanying drawing wherein:

Fig. 1 is an elevational view of the inside of my jalousie window construction;

Fig. 2 is a partial cross-sectional view taken along lines 22 of Fig. 1 showing the window sections in closed position;

Fig. 3 is a partial cross-sectional view taken alonglines 2-2 of Fig. 1 showing the window sections in open position;

Fig. 4 is a partial cross-sectional view taken along lines 4--4 of Fig. 1; and

Fig. 5 is a partial cross-sectional view taken along lines 55 of Fig. 1.

Referring to the drawings, a hand crank 1 is mounted upon the window frame 15 for moving the lever arm 2 about point 3 (Fig. 2). A worm gear (not shown) on the end of the shaft of hand crank 1 engages the gear teeth 4 aflixed to the lever arm 2 and moves lever arm 2 about point 3 when hand crank 1 is turned in the desired direction. Lever arm 2 is pivotally connected to connecting rod 5 by a shoulder rivet 6. Connecting rod 5 is, in turn, connected to vertical rod 7. v

Vertical rod 7 is pivotally connected at its upper end to an arm 8 (Fig. 4) which is rigidly connected to torsion bar 9 which extends across the top of the window frame 15 and is mounted for rotation along its longitudinal axis in the vertical sides of frame 15. If desired, the torsion bar 9 may be positioned along the bottom of the window frame 15. Another arm 10 (Fig. 5) is provided fixedly connected to the opposite end of torsion bar 9 and pivotally connected to another vertical rod 11 extending vertically down the other side of the window construction 15.

Window sections 12 (Fig. 2) comprise pairs of clip arms 13 within which the glass sections 14 are mounted.

2,865,065 Patented Dec. 28, 1958 "ice The window sections are pivotally mounted on shouldered shoulder rivets 16 on the window frame 15 in order that the window sections 12 may be opened and closed by pivoting them about their longitudinal axis. Each of the clip arms 13 is provided with a slot 17 at one end and a .clip 21 at the opposite end within which the glass sections 14 are clipped.

Pins 18 are provided on the vertical rods 7 and 11, one for each clip arm 13, at the proper places to engage the slots 17 in each of the clip arms 13. L-shaped flat or leaf springs 19, one for each pin 18 and clip arm 13, connect the pins 18 with the clip arms 13 and, as shown in the drawings, serve the double purpose of urging the glass section or pane firmly against the outer flange of clip portion 21, and of biasing the clip arm 13 in the direction to hold the lower end of its slot 17 in engagement with pin 18 (Fig. 3). p

A resilient gasket 20 is provided around the entire internal edge of the frame 15 to form an air-tight seal be tween the edges of the window sections 12 and the frame 15 when said window sections are in closed position.

In operation, to close the window sections 12 from open position, the hand crank 1 is turned counterclockwise to'raise the lever arm 2 to impart an upward vertical movement to connecting rod 5. Connecting rod 5, in turn, imparts an upward movement to vertical rod 7. Vertical rod 7, in moving upward, raises arm 8 which imparts a counterclockwise movement to torsion bar 9 (Fig. 4)

Torsion bar 9, in turning, moves arm 10, at its PPQSite end (Fig. 5), upward which imparts a similar upward vertical movement to vertical rod 11 on the other side of the frame 15. As the clip arms 13 are connected to the vertical rods 7 and 11 by the pins 18 engaging slots 17, the upward movement of the vertical rods 7 and 11 will cause the window sections to pivot towards closed position about rivets 18.

When the window sections 12 are in closed position further counterclockwise movement of hand crank 1 will cause the vertical rods 7 and 11 to continue to move upwardly and the pins 18 to move from the bottom of slots 17 (Fig. 3) towards the upper end of slots 17 (Figs. 2, 4 and 5) and in so doing to place additional tension upon leaf springs 19 and force the window sections 12 into'sealed position with one another. This tension upon leaf springs 19 will cause the window sections 12 to be urged continually into as tightly closed position as the tension of springs 19 when the pins 18 are at the tops of slots 17 will permit, regardless of any mechanical slack or high spots that may be in the window system.

I have found that if arm 10 is radially mounted on the torsion bar 9 approximately 5 ahead of arm 8, the mechanical slack will be adjusted out of the means for moving vertical rods 7 and 11 up and down for opening and closing the window sections 12 so that the ends of the window sections 12 opposite the hand crank 1 will close as tightly in sealed position as the hand crank side ends. 1

By providing individual spring means 19 on each of the window sections 12 for urging each separate window section into closed position it is possible to completely close one window section independently of the other window sections. The spring means comprising pins 18, slots 17 and leaf springs 19 securely positioned on-the clip'arms 13 permit the same amount of closing force to be exerted upon each end of each window section completely independently of the position of other window sections in the entire window system subject to the limitation that the pins 18 must be positioned somewhere between the top and bottom of slots 17.

The glass sections 14 are easily inserted into and removed from the clips 21 on the clip arms 13. To insert a 3 glass section 14, the glass section 14 is slid into the clip 21 through the open end farthest away from the slot end of clip arm 13. Projection 22 on leaf spring 19 is inserted into an opening in clip 21 and the opposite end of leaf spring 19 is lifted upwardly over pin 18.

Spring 19 is firmly held in place between the shoulders 23 and 24 provided on pins 18 by the stiffness and resiliency of the spring. The spring 19 because of its L- shaped bend also holds the end of the glass section 14 firmly within the clip 21. To remove the glass section 14, the springs 19 are first freed from pins 18 and then removed from each clip arm 13 and the glass section 14 slid out of the clips 21.

' While I have described a new and novel type of jalousie window, it is understood that the drawings and description are to be interpreted in an illustrative rather than a limiting sense, since various modifications may be made within the spirit and scope of the invention as defined by the appended claims.

I claim:

'1. In a jalousie window construction, a plurality of window sections and a supporting frame therefor, each of said window sections comprising a pane of transparent material and a supporting clip arm at each end thereof, means for pivotally mounting said clip arms on said frame, said clip arms having each a clip portion for engaging the end margin of the pane and an actuating portion including a slot, an actuating bar on each side of said window frame, said respective actuating 'bars having actuating pins projecting from the sides thereof within the slots of said respective clip arms, each of said clip arms having a spring mounted thereon and engaging one of said pins to urge it towards one end of its slot, and operating means for said actuating bars, the window sections being swung to closed position by the flexing of said springs.

I 2. A jalousie window construction as set forth in claim 1, wherein the spring on each of the clip arms is of the flat type and extends into the clip portion of said arm and bears against the pane to secure it within the clip portion.

3. A jalousie window construction as set forth in claim .2, wherein one end of the spring engages the clip portion of the clip arm and an intermediate portion of the spring engages the pane and the opposite end of the spring engages one of said pins, the spring being ten- .sioned by placing said end in position on the pin, so that when said end is removed from the pin the pressure of the spring on the pane is released thereby allowing the .pane to be released from said clip portion. 4. A jalousie window construction as set forth in claim 1, wherein the clip portions of the clip arms are provided with flanges for engaging the side end margins of the panes, said flanges being spaced apart a greater distance than the thickness of the pane, and wherein the spring on each of the clip arms is of the flat type and has a portion extending into the space between the surface of the pane and one of said flanges, said portion of the spring within said clip portion being arched so as to contact the pane and frictionally hold it within said clip portion when the opposite end of the spring is in position in engagement with one of said pins.

' 5. 'A jalousie window construction as set forth in claim 1, the clip portion of each of the clip arms being provided with a pair of parallel flanges spaced apart a greater distance than the thickness of the pane, and wherein the spring is an L-shaped member, one of the arms of which is disposed between the surface of the pane and one of said flanges and isarched so as to bring it into engagement with the surface of the pane when the opposite arm is engaged with one of said pins, said spring being removable by releasing the latter arm from the pin.

6. In a jalousie window construction, a plurality of window sections and a supporting frame therefor, each of said window sections comprising a pane of transparent material and a supporting clip arm at each end thereof, means for pivotally mounting said clip arms on said frame, said clip arms having each a clip portion on one side of said pivot for engaging the end margin of the pane and an actuating portion including a slot on the opposite side of said pivot, an actuating bar on each side of said window frame, said respective actuating bars having actuating pins projecting from the sides thereof within the slots of said respective clip arms, each of said clip arms having a spring mounted thereon and engaging one of said pins to urge it towards one end of its slot, and operating means for said actuating bars, the window sections being swung to closed position by pressure of said pins upon said springs.

7. In a jalousie window construction, a plurality of window sections and a supporting frame therefor, each of said window sections comprising a pane of transparent material and a supporting clip arm at each end thereof, said clip arms having each a clip portion for engaging the end margin of the pane and an actuating portion, means for pivotally mounting said clip arms on said frame, an actuating bar on each side of said window frame, said respective actuating bars being connected to the actuating portions of the adjacent clip arms, a shaft mounted for rocking movement in said frame and extending from side-to-side thereof, equal length arms projecting from said rock shaft near the opposite ends there- 'of, pivotalconnections between said arms and said actuating bars at the respective opposite sides of the window frame, operating mechanism for opening and closing said window sections, said mechanism being operatively connected to one of said actuating bars so as to effect movement of the clip arms connected therewith and so as to impart rocking movement to said shaft, the arm projecting from said shaft at the side of the window remote from the actuating bar to which the operating mechanism is connected being displaced angularly ahead of the corresponding arm at the other side of the window, in the direction of turning movement when the operating mechanism is actuated to close the window sections, by such amount as to so compensate for slack and torsion that when said operating mechanism is moved to close said window sections the clip arms on the opposite sides of the window frame will exert substantially equal turning moments upon the opposite ends of the several panes and cause a tight closing thereof.
